Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of milling cutter, more specifically, the utility model relates to the staggered tooth replacement formula forming milling cutter. BACKGROUND

[0002] Milling cutter is a rotary cutter with one or more teeth for milling machining. Each tooth cuts off the excess of the workpiece intermittently in turn during work. Milling cutter is mainly used for machining plane, milling hole, step, groove, forming surface and cutting off workpiece on milling machine.

[0003] Most of the existing milling cutters are provided with only one cutting tooth, so that only one cutting station can be formed on the workpiece each time. If multiple cutting processes are required for a workpiece, one milling cutter is used for multiple times or multiple milling cutters are used for multiple times, which not only prolongs the processing time, but also wastes time for tool changing and requires repositioning, so that the processing technology requirement is high, the efficiency is low, and the cost is also high.

[0004] According to the search, the utility model discloses a staggered tooth forming milling cutter with the standard milling cutter and T-shaped cutter combined into one, which can not only be used as a milling cutter, but also can be used for continuous T-slot slotting, and can complete the cutting content requiring multiple machining at one time, so that the machining efficiency of the workpiece is high.

[0005] However, when the individual tooth of the milling cutter is damaged during actual use of the above-mentioned staggered tooth forming milling cutter, the entire milling cutter needs to be replaced, which causes the waste of the intact part of the milling cutter and increases the use cost of the milling cutter.

[0009] By adopting the above technical scheme, the milling teeth can be adjusted in position on the outside of the milling cutter head as required by using the sliding limiting of the limiting groove one and the limiting groove two on the limiting strip one and the limiting strip two, and the double insertion fixing of the connecting handle and the milling cutter head by the two bolts can keep the connection of the milling cutter head and the connecting handle stable.

[0010] As a further description of the above technical scheme, the connecting mechanism comprises a plurality of positioning rods, the positioning rods are fixedly connected to the outside of the connecting handle, an insertion rod is fixedly connected to the top of the connecting handle, an external thread is arranged on the outside of the insertion rod, an internal thread is arranged on the inside of the tool handle, the internal thread is threadedly connected to the external thread, a plurality of guide grooves are arranged on the outside of the tool handle, a sliding block is slidably connected to the inside of the guide grooves, a positioning ring is fixedly connected to the outside of the sliding block, a clamping groove is arranged at the bottom of the positioning ring, the clamping groove is clamped to the outside of the positioning rod, two connecting plates are fixedly connected to the top of the positioning ring, a screw two is threadedly connected to the inside of the connecting plates, and one end of the screw two is threadedly connected to the outside of the tool handle.

[0011] By adopting the above technical scheme, the connecting handle and the tool handle are separated by the thread connection of the external thread and the internal thread, and the outside of the positioning rod is clamped by the positioning ring and the clamping groove, so that the connecting handle and the tool handle remain stable after splicing and replacement.

[0012] The technical effects and advantages of the utility model are as follows:

[0013] 1. By setting the assembled gear changing mechanism, compared with the prior art, the upper and lower movement of the milling cutter teeth outside the milling cutter head is utilized, so that the plurality of milling cutter teeth outside the milling cutter head can be staggered, and the sliding limiting of the limiting groove one and the limiting groove two and the limiting strip one and the screw one is utilized, so that the milling cutter teeth are limited in multiple directions, the milling cutter teeth and the milling cutter head are kept fastened during the milling process, and the loosening of the milling cutter teeth is avoided.

[0014] 2. By setting the connecting mechanism, compared with the prior art, the rotation of the connecting handle and the tool handle is limited by the plurality of positioning rings and the clamping grooves, so that the connecting handle and the tool handle are screw connected through the external thread and the inserting rod, good connection stability is maintained, the damaged part is only replaced when the milling cutter is damaged, and the use cost of the milling cutter is reduced.
